where perm defines the electric permittivity of the fluid(s), charge defines optionally the volume electric charge density and GfsElectricProjectionParams optionally controls the accuracy of the numerical solution of the Poisson equation for the electric potential Phi.

Electric volumetric forces can be added to the momentum equation using

although it is only available if the charge function is a direct injection of a pure variable (i.e charge = Rhoe). Additionally, the implicit scheme for the conduction term is incompatible with other implicit schemes applied on the same variable (i.e. GfsSourceDiffusion Rhoe Diffusion).
